Question

Here is my data

1. Look at the % deviation section of the calculations table. Choose the two samples with the least % deviation. Write the values from the table for the [SCN-]eq for these two:
__________M, __________M. Use the equation: [SCN-]initial - 2[[Fe(SCN)2+] = [SCN-]eq  to show what these values would be if the reaction equation in question 1 (Fe3+(aq) + 2SCN-(aq)<-->Fe(SCN)2)+(aq)) is the actual equation for this equilibrium. (Show your work.)

2.Use the values calculated for the [SCN-]eq in question 3 and the Kc expression from question 1 to calculate the values of Kc for the two samples under the conditions raised by these questions. Show the units along with the numerical value for the two Kc's.
Divide the larger number by the smaller number, and multiply by 100 to see the percentage differences between them. Are they farther apart than the two K's you used for the concentration data? If so, this shows that the law of equilibrium does not apply if the stoichiometry used is not the actual stoichiometry of the reaction.

Sorry, data given in the question is not clearly visible. I can’t figure out numbers written on the sheet.
